par_usage_goal.wlm

This file, in combination with the global arbiter configuration file in the

next section, can migrate cores across HP-UX Virtual Partitions and/or

nPartitions based on usage goals. The way WLM manages cores depends

on the software enabled on the complex (such as Instant Capacity, Pay

per use, and Virtual Partitions).

Activate the WLM configuration file in each partition. However, you only

need to activate the WLM global arbiter’s configuration in one partition.

# Name:

# par_usage_goal.wlm

# Version information:

# $Revision: 1.4 $

# Caveats:

# DO NOT MODIFY this file in its /opt/wlm/examples/wlmconf location!

# Make modifications to a copy and place that copy outside the

# /opt/wlm/ directory, as items below /opt/wlm will be replaced

# or modified by future HP-UX WLM product updates.

# Purpose:

# This example, used with par_usage_goal.wlmpar, demonstrates WLM’s

# ability to resize HP-UX Virtual Partitions and/or nPartitions

# based on workload usage. The configuration is strictly host-based,

# not supporting FSS or PSET groups; thus, applications within a

# partition are treated as a single workload. Because the utilitypri

# feature is not used in par_usage_goal.wlmpar, the total number of

# active cores remains constant, but the CPU allocations for partitions

# change automatically to meet each partition’s usage needs.

# The way WLM manages CPU resources depends on the software enabled

# on the complex (such as Instant Capacity, Pay per use, and Virtual

# Partitions.)

# Dependencies:

# This example was designed to run with HP-UX WLM version A.03.00 or

# later. (A.03.00 was the first version to support strictly
